Will it thunder and lightning in winter?
Thunder in winter, commonly known as "thunder in winter" or "thunder in winter", referred to as "winter thunder". Thundering all year round is a normal weather phenomenon, but there are fewer thunderstorms in autumn and winter. Although the weather of "thunder in winter" is not common in autumn and winter, it is only a weather phenomenon.
Although the phenomenon of "thunder can't stop winter" is rare, it is not unique, and it occurs in many parts of the country. If the weather is cold and hot, there will be more opportunities for the phenomenon of "thunder and winter". Under the influence of strong warm and humid airflow and strong cold air, the warm and humid air in the lower layer was forced to rise, resulting in strong convection, which created conditions for the formation of lightning. After the "beginning of winter", "thunder entered the winter" appeared.
How is lightning formed?
The cause of lightning is generally thought to be that various particles in the cloud accumulate charges due to collision and friction. When the amount of charge reaches a certain level, which is equivalent to the voltage between clouds or between clouds and ground reaching or exceeding a certain value, the local electric field strength will reach or exceed the electrical breakdown strength of air at that time, thus causing discharge.
Electricity in the air rapidly heats and expands the air through discharge, and is compressed into plasma due to the expansion, thus generating a special component of lightning (sound of shock wave).
The current of lightning is very large, the peak value can generally reach tens of thousands of amperes, but the duration is very short, generally only a few tens of microseconds. Therefore, the energy of lightning current is not as great as expected.
